[gradsusr] Templating 3B42_daily.*nc TRMM files

[Charles Seman]

Matei,

One possibility is in your VARS "hrf" definition: try "t,z,y,x"... or 
better yet, have you tried the "sdfopen" templating method?  Please see 
a recent post I sent containing an email attachment with an email 
Guilherme Martins sent me for an example of how to do this... For more 
info on sdfopen templating: 
http://grads.iges.org/grads/gadoc/gradcomdsdfopen.html  If neither of 
these work, a "chsub" templating method worked for our TRMM 3B42 
3-hourly regridded precipitation datasets 
(http://grads.iges.org/grads/gadoc/templates.html, GrADS template ctl 
file attached).

Hope this helps,
Chuck
